I think the difficulty options should be lain out like this:
Your damage to Others: From 1\6 to 6x.
Enemy damage to you: 1\6 to 6x.
Others damage to others: 1/6 to 6x.
hardcoe mode: On/Off
You would be able to open the hardcoe tab and choose which options in particular to choose, eg, arrows have weight, all potions heal over time etc.
Thoughts?
